Hey everyone!
I just discovered a new desktop vaporizer called the ForgeHaven, and I thought I’d share it here because the concept looks really interesting. I’ve personally never seen this approach used in a dry herb vaporizer before.
Instead of simply heating the herb while you draw air through it, the ForgeHaven first creates a sealed vacuum environment, removing around 60–70% of the air from the chamber. The herb is then heated and the vapor collects inside the sealed chamber rather than being immediately mixed with a continuous stream of room air.
So the idea is that when you inhale, you’re drawing from a chamber already filled with concentrated vapor rather than producing and diluting the vapor with fresh air at the same time. According to ForgeHaven, this should mean denser vapor, less oxidation and better preservation of terpenes and flavor.
Another really unusual part is the temperature range. They say lower settings around 100°C favor flavor and lighter aromatic compounds, around 130°C gives a balance between flavor and vapor, and you can go higher when you want more density and extraction.
The bowl can also hold up to 1.5g, which is huge. 
I’m really curious whether this is mainly a slow session device where you let the vapor accumulate, or if it can actually produce massive clouds and extract quickly. Unfortunately, I haven’t found a proper vapor-production video yet.
Then there’s the part that hurts: the price. 
It’s currently around $594 USD, with a regular price listed at $750 USD. Expensive vaporizers definitely seem to be becoming a trend lately. At the same time, I can understand it to some extent: many of these innovative devices are being developed by very small companies producing in low volumes. R&D, tooling and development costs have to be recovered over a relatively small number of units. Still… $600–750 for a vaporizer definitely hurts!
Overall, though, this is one of the more unusual approaches to DHV technology I’ve seen lately, so I figured I’d start a discussion here and see what everyone thinks.

Has anyone here seen or tried something using a similar vacuum-based concept before?
Quick note: I haven’t been able to independently verify much information about the company behind ForgeHaven yet. Their website doesn’t provide many details about where they’re located or where the devices are manufactured/shipped from, so please do your own research before ordering.
Personally, I’m interested in the technology, but I’m not comfortable placing an order yet until I know more about the company, its location, and the product itself. Hopefully we’ll get more information soon.
A lever espresso machine can pull 9 bars with just a small oring seal. The video shows them pulling only 1 bar! Get the piston size small pinhole inlet opening right, you can pull that pressure while passing air through the herb the whole time. Hmm… and if you let the vapour rest and cool, you can open a tap and let it flow down into a sealed (windproof still air) glass final chamber for theatrics, kind of like pouring a proper espresso.
I’m really curious to see how it performs.
